TLS Negotiation failed, the certificate doesn't match the host.

Hi,

From 2 days ago, suddenly I'm starting to get this on outgoing mail:

TLS Negotiation failed, the certificate doesn't match the host.

If i try to change password and connect again the outgoing SMTP server to vestacp server it says invalid credentials. If I connect to insecure connection, it works though.

Any ideas?

I've found the solution (workaround) for this. The solution is to append the .ca file details in to the .crt file. The solution is described here, http://css.lk/blog/8/gmail-send-mail-as ... ed-on-exim

Wish Exim team will introduce a parameter to point out the CA certificate details, soon.

Hope this helps.

I'm having this trouble right now...

For band-aid fix I'm using my panel domain as mail server.

My vestacp uses domain.ext, for example.
My clients domains are: client1.ext, client2.ext...

Client One <[email protected]>
E-mail sent by: domain.ext
